PCI (PLANEX) USB 56K Analog Modem PL-US56K, used item. I used it to send faxes on Windows 10. Comes with a 2-meter phone cable and an extension socket. It's an old item, so manufacturer support has ended, but the Windows 10 driver is distributed on the manufacturer's website. Please check the manufacturer's website for details. Operation on Windows 11 has not been confirmed, but it was recognized by the PC (last two photos). - Model Name: PCL-USB56K - Connection Type: USB - Cable Length: Approximately 2 meters Thank you for looking.
